Seaside City is an adult sandbox dating sim set in a sprawling coastal metropolis where players meet more than 50 unique characters, pursue branching romances, and uncover a larger mystery while shaping how explicit encounters play out. You start as an orphaned tenant in a wealthy family’s estate and slowly learn that your comfortable new life comes with a cost. The title emphasizes player choice: most characters, kinks and dialogue paths are optional, and a flexible Dom/Sub mechanic changes how relationships and sex scenes resolve, making the experience attractive to players who want both narrative depth and adult content.
